A Tustin woman was sentenced today to two years and eight months in state prison for setting up two robberies of Orange County Rite Aid stores where she worked as a supervisor.

Cynthia Ongamsing-Jenkins, 43, pleaded guilty Feb. 24 to two felony counts of grand theft, according to court records. Orange County Superior Court Judge Derek Johnson sentenced Ongamsing-Jenkins to two years in state prison on one count and eight months on the other.

Two charges of second-degree burglary, false report of a felony to police and a sentencing enhancement for the use of a dangerous weapon were dismissed.

Jenkins was a supervisor at a Rite Aid store at 2300 Harbor Blvd. in Costa Mesa. She called Costa Mesa police Nov. 11, 2007, to report that she and a co-worker had been robbed, according to the District Attorney’s Office.

Jenkins said two robbers held up the store with a handgun and ordered them to turn over cash from the register and a safe, according to prosecutors.

The robbers forced Ongamsing-Jenkins’ co-worker into a store cooler before making off with about $5,500, according to the District Attorney’s Office. Surveillance video recorded the holdup, but the robbers could not be identified.

Ongamsing-Jenkins was working as a floor supervisor at another Rite Aid at 23829 Del Prado in Dana Point when it was robbed June 20, 2009, according to the District Attorney’s Office.

Ongamsing-Jenkins told Orange County sheriff’s deputies she was walking through the parking lot of a Bank of America in Dana Point with a deposit bag from the Rite Aid where she worked when a man pushed her down and took the bag, which had about $20,000 of the store’s deposits for that week, according to prosecutors.

Someone called 911 when they heard Ongamsing-Jenkins yell for help.

Sheriff’s deputies investigating the case retrieved two suspicious text messages on Ongamsing-Jenkins’ cell phone that led them to believe she helped stage the Dana Point robbery, according to the District Attorney’s Office. She later confessed to investigators that she set up both robberies, according to prosecutors.
